Liquid Controls Group's positive displacement meters provide exceptionally accurate service when using their unique positive displacement metering principle, even under variable operating conditions (changes in temperature, pressure and viscosity). (read more)

The Valcor solenoid operated metering pumps are positive displacement devices where the effects of fluid pressure, density and viscosity are minimized, as the flow rate is almost entirely dependent on the volume displaced by the piston during each stroke and on the number of strokes per unit time. These pumps thus provide flow accuracies greater than those of conventional pumps or flow valves (read more)

For more than five decades, NETZSCH has manufactured positive displacement pumps worldwide. Designed specifically for difficult pumping situations, NETZSCH pumps range in size from the industry's smallest metering pumps to high volume pumps. In 1951, the NETZSCH Group acquired the Progressing Cavity... (read more)

Hydra-Cell's unique sealless, hydraulically-balanced diaphragm pump handles difficult applications eliminating problematic mechanical seals, packing or magnetic couplings. The compact design reduces space requirements and acquisition costs, and the multiple diaphragm configuration provides non-pulsing flow for accuracy, linearity and repeatability. (read more)
